@Cro_Pittt The guns have identical DPS, but the L-star has 2x headshot multiplier. The Volt ADS speed is basically double the L-star.. How ever you can hip fire it, it's bullets are much larger than the volts so it's better for hip firing anyway. If you land a few headshots with the L-Star you will outshoot the volt every single time.
I'll use it and try to get some clips of me melting squads with it. First week of this season I posted a 1772 damage round with it and it was 2vs3 the entire match for my squad.
